The invention discloses a display panel, a display device and a color film substrate, and belongs to the field of displayers. A special-shaped fringe area of the display panel comprises multiple edgepixels, a shading structure is arranged in the special-shaped fringe area and comprises multiple shading units which are in one-to-one correspondence with the multiple edge pixels. The multiple edge pixels all comprise multiple sub pixels, the shading areas of the shading units on the multiple sub pixels of the same edge pixel are the same, the phenomenon that the pixels generate color cast can beprevented, and meanwhile orthographic projection of the shading units on each sub pixel covers the end, close to a non-display area, of the corresponding sub pixel in the pixel column direction, boundaries of the orthographic projection and the corresponding sub pixels are arcs sinking to the non-display area, the arc design can make the weakening effect of sawteeth of the special-shaped edge area more obvious, and the edge sawtooth effect of the display panel is lowered.
